Phosphatidylinositol 3−kinase
Phosphoinositide 3-kinases (PI3Ks), also called phosphatidylinositol 3-kinases, are a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. PI3Ks are a family of related intracellular … See more The discovery of PI3Ks by Lewis Cantley and colleagues began with their identification of a previously unknown phosphoinositide kinase associated with the polyoma middle T protein. They observed unique … See more The various 3-phosphorylated phosphoinositides that are produced by PI3Ks (PtdIns3P, PtdIns(3,4)P2, PtdIns(3,5)P2, and PtdIns(3,4,5)P3) function in a … See more Many PI3Ks appear to have a serine/threonine kinase activity in vitro; however, it is unclear whether this has any role in vivo. See more All PI3Ks are inhibited by the drugs wortmannin and LY294002, although certain members of the class II PI3K family show … See more The PI3K family is divided into four different classes: Class I, Class II, Class III, and Class IV. The classifications are based on primary structure, regulation, and in vitro lipid substrate specificity. Class I Class I PI3Ks … See more PI3Ks have been linked to an extraordinarily diverse group of cellular functions, including cell growth, proliferation, differentiation, motility, survival and intracellular trafficking.
